BOBBIN-SKEWER.

Specification of Letters Patent.

Application filed October 14, 1916. Serial No. 125,684.

To all whom it may concern:

Be it known that I, EDWARD D. ROY, a citizen of the United States of America, and a resident of Greenville, county of Greenville, State of South Carolina, have invented certain new and useful Improvements in Bobbin-Skewers, of which the following is a full and clear specification.

This invention relates to that class of skewers employed for holding bobbins in roving machines. In this type of skewer, as is well known, the skewers are journaled vertically in a creel, the upper end of the skewer being held loosely in a top bar and the lower pointed end of the skewer being provided with a pointed head whose point rests in a cup or socket formed in or mounted on the bearing rail of the creel. The bobbin is slipped down over the skewer and rests upon an annular shoulder positioned at the lower end of the skewer. There are a number of objections to this type of skewer that my device completely overcomes, as more fully hereinafter set forth.

In the drawing Figure 1 is a side elevation partly in section; and

Fig. 2 is a transverse section showing my preferred construction.

In the drawing, a designates the metal staff of the skewer, this staff being pointed at b, exactly alike at each end, so that either end of the staff may rest in the lower hearing cup when the skewer is in use.

Afiixed to the staff is a pair of metal disks 0, these disks being located at equal distances from the respective pointed ends of the staff. These two separated disks afford a support for the bobbin (Z, the bobbin being slipped down over the same, the inwardly-extending flange c at the upper end of the bobbin resting on the upper disk. To facilitate the entrance of either disk into the bore of the bobbin, the outer face of each disk is made conical at f, the taper being toward the adjaoent pointed end of the staff. Vith this construction, it will be observed that either end of the staff may be used as the bearing end and that the bobbin may be slipped on to the skewer from either end, thereby so facilitating the insertion of the bobbin on the stafi as well as the placing of the loaded skewer into the creel that considerable of the time of the attendant will be saved.

This type of skewer has many other advantages over the old wooden type. Likelihood of it being shattered by being dropped loaded on the floor of the mill is entirely eliminated. The separation of the skewer staff from the usual pointed head is also entirely avoided. It sometimes happens that the ordinary wooden skewer, by reason of its lightness, will occasionally jump or be pulled out of the bearing cup; with my device, it being made of heavier material than wood, this accident is not likely to occur. A disadvantage of the present wooden type of skewer is that it gathers lint, thus occasionally breaking the thread and resulting in the loss of the time required for cleaning the accumulated lint from the head; this disadvantage is entirely done away with by employing a metal skewer in view of the fact that the surface of the metal can easily be made so smooth that lint will not adhere to it. My improved skewer will also run with a more even tension than the wooden type and, therefore, will not stretch the roving, which stretching causes the roving to break or produces light work and makes singlings.

It will be observed also that with my construction the bobbin is not supported at its lower end, as is usual in this type of bobbin, but on the contrary is suspended from the upper disk, the lower disk serving to steady the lower end of the bobbin and thus prevent it wabbling; in this way, I provide a steady and sure support for the bobbin.

Having thus described my invention, what I claim is:

,A. reversible skewer for creel bobbins, consisting of a metal staff pointed at each end and provided with a bobbin support equidistant from the ends of the staff.

In testimony whereof I hereunto aflix my signature.

EDWARD D. ROY.
